Current Foci:

Since 2010,  I have been focusing my energies on the US Materials Genome Initiative, a multi-agency initiative designed to create a new era of policy, resources, and infrastructure that support U.S. institutions in the effort to discover, manufacture, and deploy advanced materials twice as fast, at a fraction of the cost. More information about the MGI can be found at the MGI home page.  In my role as Director of the NIST Materials Genome Program, I am working with a government-wide team to build out the materials innovation infrastructure needed to realize the goals of the initiative.  NIST, in particular, has an outsize role to play in achieving those goals.  More information about the NIST effort in support of the MGI can be found at the NIST MGI home page

Research Interests:
My research is broadly concerned with developing both models of materials phenomena, and the tools to enable the solution of these models. Specific foci include solidification, pattern formation, grain structures, wetting, diffusion, and spreading in metals.

I have been employed at NIST since 1992,  in the Metallurgy Division and its successor the Materials Science and Engineering Division, within the Material Measurement Laboratory. I am also one of the co-founders, and the current Director, of the NIST Center for Theoretical and Computational Materials Science.

For a discussion of the the multitude of phase field modeling projects I have been involved in, as well as work by others in the CTCMS on this interesting topic.  Another great resource on Phase Field Modeling can be found on the NIST Center of Excellence, the Center for Hierarchical Materials Design, phase field modeling benchmarks page.
